CBD And Cancer: Exploring Its Potential As A Complementary Therapy

CBD & Cancer

Living with cancer is challenging in so many ways – not just for the person who has cancer, but also for their carers, loved ones and friends. With cancer rates growing around the world, medical professionals, scientific researchers and even cancer patients themselves are constantly looking for effective complementary therapies, alongside traditional treatments like chemotherapy and radiotherapy, to help alleviate symptoms and improve overall wellbeing.

The potential of CBD’s role in managing cancer symptoms has seen CBD become one of those complementary therapies that has become hugely popular among cancer patients worldwide.

In this blog, we’ll look at the science behind CBD and cancer, its potential role in helping to manage and alleviate cancer symptoms and side effects from traditional medications, how to use CBD oil and edibles for cancer patients, and the safety considerations when using CBD in cancer care.

The Science Behind CBD And Cancer

CBD works in the body by affecting receptors in the endocannabinoid system, helping to control how messages are sent between cells, and keeping the body balanced and healthy. Some scientific research has explored the potential of CBD in cancer treatment and symptom management. While studies are ongoing, preliminary evidence suggests that CBD may exert anti-cancer effects in various way, including:

  • Antiproliferative properties: CBD has been shown to inhibit the proliferation of cancer cells and induce apoptosis (programmed cell death) in certain cancer types.
  • Anti-inflammatory effects: CBD possesses potent anti-inflammatory properties, which may help reduce inflammation associated with cancer progression and treatment-related side effects.
  • Pain relief: CBD’s analgesic (pain relieving) properties make it a promising adjunct therapy for managing cancer-related pain, improving quality of life for patients undergoing treatment.

While more research is needed to understand the full extent of CBD’s anti-cancer properties, emerging evidence underscores its potential as a complementary therapy in cancer care.

CBD’s Role In Managing And Alleviating Cancer Symptoms

Beyond its potential anti-cancer effects, CBD shows promise in managing various symptoms commonly experienced by cancer patients, including:

  • Pain: CBD’s analgesic properties make it effective in alleviating cancer-related pain, whether due to the disease itself or as a side effect of treatments such as chemotherapy, radiation therapy or surgery.
  • Nausea and vomiting: cancer patients often suffer from severe nausea and vomiting. CBD may help relieve chemotherapy-induced nausea and vomiting, which can significantly improve quality of life.
  • Anxiety and depression: cancer diagnosis and treatment can affect mood and mental wellbeing, often leading to mental health concerns such as anxiety and depression. CBD’s anxiolytic (anti-anxiety) and antidepressant effects may help mitigate these symptoms and promote overall mental wellbeing.

CBD Oil For Cancer Patients

CBD oil is one of the most popular forms of CBD, offering a convenient way to incorporate CBD in accurate and customisable doses as part of a patient’s wellness regimen and symptom management. When considering CBD oil for cancer patients, taking it sublingually (under the tongue) is a popular option because it allows for rapid absorption into the bloodstream and has the potential for quick relief from some symptoms, which can be particularly helpful for those who struggle with nausea, vomiting and keeping food down.

CBD oil can also be added to foods or beverages, making it suitable for patients who prefer an alternative to traditional oral medications.

CBD Edibles And Cancer

When it comes to the potential benefits of CBD edibles and cancer relief, CBD edibles such as gummies, chocolates and honey, offer a discreet and palatable way to consume cannabidiol. While the onset of effects may be slower compared to other methods of administration, CBD edibles provide prolonged relief, making them ideal for managing symptoms throughout the day.

Additionally, CBD edibles offer precise dosing, allowing patients to tailor their CBD intake to their individual needs. Whether used as a standalone therapy or in conjunction with other treatments, CBD edibles offer a versatile and effective option for cancer patients seeking symptom relief and improved wellbeing.

Safety And Side Effects Of CBD In Cancer Care

Safety is paramount when considering the use of CBD as a complementary therapy in cancer care. While CBD is generally well tolerated by most people, some may experience side effects, including:

  • Dry mouth: CBD can inhibit saliva production, leading to dry mouth, which can be alleviated by staying hydrated.
  • Fatigue: Some patients may experience fatigue or drowsiness, especially at higher doses of CBD.
  • Drug interactions: CBD may interact with some other medications.

It is essential for people with cancer to speak with your treating oncologist or cancer specialist before using CBD as part of a complementary therapy regime, especially cancer patients undergoing chemotherapy, radiotherapy or taking any other medication.


From its potential anti-cancer effects to its role in managing pain, nausea and mental health issues associated with cancer, CBD shows promise as a versatile complementary therapy in cancer treatment regimen. While further research is needed, the potential for CBD as a safe and effective complementary therapy is truly exciting.

By understanding the science behind CBD and cancer, as well as its safety considerations, healthcare professionals and patients can make informed decisions about its use as part of a holistic approach to cancer care. Once again, it is essential to consider the safety and side effects of CBD in cancer care, so ensure that you speak with your medical team before using any CBD products.
